PROBLEMS OF FROST AND THAW IN PAVEMENTS /IN FRENCH/

AFTER OUTLINING THE CHARACTERISTICS OF THE CLIMATE IN FRANCE, THE AUTHOR PRESENTS STATISTICAL DATA ON LOWEST FREEZING TEMPERATURES RECORDED OVER A FEW HUNDRED YEARS, ESPECIALLY THOSE TAKEN DURING THE WINTER OF 1962-63 (A FROST INDEX MAP FOR FRANCE IS INCLUDED). THE MAIN CHARACTERISTICS OF FRENCH SOILS MOST SUSCEPTIBLE TO FROST (CHALK, SILT AND LOESS, MARL, AND WEATHERED SOIL) ARE MENTIONED. A DESCRIPTION IS GIVEN OF THE PRESENT PROTECTION SYSTEM BY MEANS OF "BARRIERES DE DEGEL" (TRAFFIC RESTRICTIONS ENFORCED DURING THAW): NATURE OF THE RESTRICTIONS IMPOSED, CONDITIONS OF ENFORCEMENT, INFORMATION TO THE PUBLIC, TESTS CARRIED OUT TO SELECT DAYS FOR IMPOSING AND REMOVING THAW RESTRICTIONS. THE DESIGN OF PAVEMENTS TO RESIST FROST IS DISCUSSED, BASED ON OBSERVATIONS MADE DURING THE WINTER OF 1962-63 (INFLUENCE OF THE PERMEABILITY OF THE SURFACING AND PROXIMITY OF THE WATER-TABLE). THE ADVANTAGES OF RIGID AND SEMI-RIGID PAVEMENTS OVER FLEXIBLE PAVEMENTS, FROM THE POINT OF VIEW OF FROST RESISTANCE, ARE STRESSED. /LCPC(A)/RRL/
